Figure 4. VSL#3 and conjugated linoleic acid (CLA) regulate colonic lamina propria lymphocytes (LPL) and colonic gene expression.

Expression of toll-like receptor-4 (TLR-4) was assessed by quantitative real time RT-PCR (A). LP macrophages were immunophenotyped to identify their production of MCP-1 by intracellular staining and flow cytometry (B). Values are means ± SEM, n = 10. Statistically significant differences (P<0.05) when compared to Cre−, Cre+, or both control (CONT) mice are depicted with an asterisk, two asterisks, or the # symbol, respectively.
